Product Description
Seismograph Geophones CDJ Vertical Geophone
CDJ Series Digital Seismic Sensor (Geophone) are available frequencies from 1Hz to 100Hz vertical and horizontal direction, and geophone-consisted three-component geophones, borehole geophone, tomographic imaging geophone series with stable performance, high fidelity and consistent quality in oil, gas exploration and other fields
- 1~3Hz geophones applied for deep seismic prospecting, natural earthquake surveillance and prediction, pulse and microseismic measurement for bridge and highways, etc.
- 4~100 Hz widely used to seismic prospecting of petroleum, coal, metallurgy, defense engineering and etc.
- High sensitivity, low-distortion, reasonable damping coefficient, good linear response, good parameter conformity, higher resolution and excellent waterproof property.
- Small-sized, easy to install, easy to operate, large ambient temperature range, can meet the demand of multi-wave component seismic data acquisition technology.
